Whjl

e my machine has been especially lanned and adapted to make a paper boxliom. a blank of peculiar sha e, such as will be more especiallydescribed slow, its'r'nechanisms may be adapted to make boxes fromblanks of other shapes the peculiar features of the mechanisms todescribed being as peciall adapted to make a box having particular ysquare edges and folded with great accuracy. These features are attainedin my machine by careful registration and by the eculiar characteristicsand operation of the ormer and follower which grip the blank while inthe carrier and before any portion of the folding operation takes placeand which areprovidedwith coo eratin surfaces adapted to stretch the bank a ong its bottom edges, so that it retainsa right-angled shapearound the bottom, causing the bottom tb remain flat when the box iscompleted.

Another peculiarity of my machine lies in the fact that the blank iscarried from the blank pile to the former in a recess in the carrier,which recess is of the shape of the blank, so that the carrier may slideunder the blank pile and register therewith without.

any such interference as would exist if ga es were provided to definethe osition of t e blank open the carrier. T us the blank when' firstreceived irom the bottom of the pilc takes a predetermined position on;the carrier, which gosition' enables it to register a wit the'formsrwhenthe carrier has reached its forward osition.

Another peculiarity 0 this machine lies in the fact that the mechanismwhereby the blank is folded' abont'the'former is carried by the carrierand forms, in fact, a portion of the support biglxioans' of which theblank is retamed wit the recess of the. carrier, so that the blank isreceived by the carrier in the eX act position with relation to thefolders which .it is to maintain when the folders begin thefoldingnperation.

Another peculiarity of mymachine lies in I the use of aformat which. atthe time of on line 7 7 oi forming the blank about it is located at oneextrenuty of its stroke, its bottom surface being on substantiall thelevel of the opposing surface of the b ank. Thus the entire formingoperation by means of which the blank is formed about the former takesplace Without any movementof the former, the blank being clamped theretoby a clamp, which its 11 ward movement raises that portion of the lankwhich is to be clamped to the end oftho former very little, if at all, y

from its recess in the carrier. another peculiarity of my invention isthe stripping mechanism whereo the completed box is stripned from theormer, which.

stripping mechanism is located upon and moved with the pressers, b.meansof which the gumined flanges of the lank are pressed togetherandagamst theformer, to cause a thorough adherence of the one flange to theother.

'ihcfoldin mechanism. as shown isconstructed as ollows: G is a formeraround which the blank is to be folded by suitable means It is mountedon the end of a stem G, whereby it is connected with averticallyreciprocating frame comprising a cross'bar G mounted on theupper endsof two vertical slides G connected at the bottom by a crossbarG, said slides sliding in vertical uides G supported by means of flangesG jbolted to the table A. In order to gir s to this frame and the formerits reciprocating movements at the proper time, there is attached toeach slide G a stra G having thereon'a stud G, can ing a li G, adaptedto swirl" on said stu G The lowercnd of thislin is connected by acam-lever G with a csigG flthe fulcrum of this lever being in a standardGr mounted-on the cross-brace A l The cane groove of the cam G isconstructed in the ordinary manner to give the former the movementshereinafter described. The former G is nom nally in its highest osition,as shown in FigsZ, 3, and 4, in whic position" its bottom'is onsubstantially the level of the oppos ing surface of the blank carried bthe carrier E; and in the machine, as s own, the blank is folded aboutthe former while the former is in this position, from which osition itmoves to carry the folded blank own to the presser below, by which thehorde complctcd.

Before the folding operation takes place the blank while still in thecarrier is gripped against the bottom of the former G by means of afollower H of peculiar construction. (Sec 5, 6, and 7.) This follower,as shown, consists of two parts, s bed-piece h and. a yielding clamp h,su ported upon springs h, which normally hol it away from the dpiece it,each spring surrounding aguide gin 8 Guides A are provided, betweenwhich the bed-piece It moves. The bed-piece it also carries two lips it,theends of which are be low the normal level of the clamp h, but whichwhen the clamp it engages t e former G may procct somewhat beyond theupper surface of t c clamp h depending upon the ressure exerted, thusbecoming effective to old certain rtions of the blank, as will hebelowdescn d.

The clamping pressure giv'ento the follower issufficient to cause the clam h to yield somewhat, enough to cause the'ps h to protrude beyond the clamp h and turn up the ears 2 of the blankagainst the former, holding them there until the sides 3 and 4 of thebox have been thrown up and the flanges 5 and 6 have been foldedsufficient] far about the former to insure the holding 0 the ears,2 inplace. The follower H is then withdrawn slightly, not sufiiciently, torelease its hold upon the part 1 of the blank, but'enough to withdrawthe lips h from above the level of the clam h so that they will notinterfere with the rther folding operation.

In describing the further 0 eration of folding it may be as well tostate ere that I have called the under surface of the former the bottom,the wider vertical sides thereof the sides, and the narrower verticalsides While this nomenclature is not exact, it is concise and tenable.To the corresponding parts of the box I give the same names, the endsbeing made of the overlapping flanges.

In order to insure an absolutely squar edge around the bottom 1 of thefinished box, I have found it desirable to give to the'botis in t emachine the angle between its sides and ears and its bottom will besomewhat thus causing a slight box to remain in I lane at right anglesto the sides and ends a ar the box has been rebulge as has been um,heretofore.

Not onlyis the carrier recessed at d, as described above but the bottomof the recess is 'formed by foldinglates, on which the blank is receivedfrom t e hopper and on which it rests until its sides are fielded bymechanismflctingj upon these plates. The carrier thus not only serves asa carrier in the sense that it conveys the blank from a receiving.position a position under the es as a su port for the blank at*the'beginni1ig of the fol operationsandiaavframe in which the fol era areThe folding-plate J for the side 3 and are h u on a cross-rod j, mountti-n the carrier just clear of the Tedgejof the openingthrough which theformer G carries the blank, as will be described later. This plate J is,slotted at J, and in these slots are hung on the rod two shearplates Jthe front edges of whic are curved slightly orsmoothed ofi, so that theywill not cut the blank. In order to prevent the shear- V lates J fromfalling through the slots J in t e plate J when it is in a horizontalrovided with beveled ends apted to enga e larly beveled ends to theslots J (See Fig. 2.) The slotsJ' in the plate J are so located withrelation tothe ends of the former G that when the late J is moved into avertical osition in olding the blank b means to be ascribed theshear-folders on being pushed through the slots J will pass one oneach-side of the former G and sufficiently near thereto to cause thesides of the blank 5, which is lifted by the ,la'te ilduringmhis 0 Veration, to be turn -or folded a I ut t e ends of the former G.

The side 4 of the blank, with its flanges 6, rests ontwo plates K K e chof which is hung upon a stud k, w kit studs groject from the inner wall.of the opening in t e carrier and together form the axis for the folder,which is made up of these twb plates. Each plate K carries a wing Khinged thereto, this construction being such that when these platesK arelifted into a vertical their wings K ma y be turned about e ends of theformer. I prefer to make this winged folder in the form of two plates Keach car- 1- ing a wing Kf as above descri in orwith simi- 'tion i erthat the movement of the carrier may overlap that of the former in itsupward stroke, thus saving some time in the opera-. tion of themaohine;but it is evident that Both this'fol Ewan find the folding of the side 4an are caused :in

K, after which the wings K are operated to turnthe fl 6, of the b ankabout :the ends of the former. .as this 1 operation is timed to takeplace after the side 3 and its flanges 5 have been folded, the gummedsurfaces of the flanges 6 of the blank will overlap the flanges 5 andears 2, so that by the application of sufficient pressure thereafter theflanges 6 will be caused to adhere to the flanges 5 and ears 2. Beforethe application of pressure takes place the sheen plates J must be firstwithdrawn or the folded blank be carried out from between them unlessthey are sufficiently small not to interfere with the pro or movement ofthe gummed flanges 6 an the flanges 5. As soon as the folders haveturned the blank about the former suificiently far to cause the flangesto hold the ears 2 in lace, the bed-piece h is withdrawn sufficient y towithdraw the lips 711" to the level of the clamp it, so that they willnot interfere with the further folding operation, but without, however,causing the clamp to release the blank.

The inner walls of the opening in the carrler E are suitably recessed tosupport the plates J and K and the wings K in substam tiall v horizontalposition and to hold the sheanplatcsd so, that their upper surfaces willbe at substantially the level of the plate 5. These plates J and K are.preferably'operated in the following manner: Just below the table A andon one side oi the carrier E are located two pinions L Z. Each pinion ismounted on a rock-shaft L Z, journaled in t e table A, these pinionsbeing in mesh and t' e inion Z being slightly smaller than thepinion .4.Each rock-shaft carries a rocker-arm it's; The arm 1" carries at itsfree end a cross-Bar j suificiehtly long to engage the'under sids cf theshear-plates J and provided at each end with rollers 7' so that as therocker-arm is given a movomentthrough an arc ofiisay, ninety degrees thecross-oar rollers strike the shear-plates .3 and drive them through thefoldin plate J after which the. cross-bar striking t e plate 5 liftsboth it and the shearplates, together with the side? of the blank, untilnot only does the side 3 strike the former G,,' hutithe'fiangcsfi arefolded about the ends of the former." Hooks j iare attached to thdundcrside of the plate J, with which the cross-bar j engages to withdraw} theplate J at tie proper time; Each shearplate isproviied with a stop j tokce it rom slipping through the slots J. he rocker-arm 1cisle-onstructed in a somewhat similar inanncr, but its extremity ispreferably cohstructed as shown'iniFlgs. 14, l5

and 16'. The arm k carries a head k, hav ing projecting therefrom twofingers 7:, one

on each, side ti tile headand so far apart that they will not enfi agewith theplatcs K,

with the wings I. The center of the head A" is recessed to rlecoivc astud k, which car? rirs the plate-lifting portion of the head,consisting f a cross-bar 7c, su )ported on sail stud k and carrfving ateac end a roll is.

the I of the box shall not bulge out of shape I pre- The stud is is'heldin a position slightly in advance of theiingers Ir by means of a springis, the strength of which is adjustable within the head k Thisconstruction is such that as the rocker-arm 7c is thrown u the-rolls kwill first strike the plates K and'lift them and the part 4 of the blankwith its flanges 6 into a vertical position. The continued move ment ofthe rocker-arm is will cause a depression of the crossbar 1c and itsstud Yr within the head, this pro'ecting the fin ers 16 against thewings and causing t em to turn about the corners of the former and foldthe flanges 6 toward the flanges 5 already in place. The relation thenestablished bc-v' tween the fin ers it and the cross-bar k is indicatedin F1g. 16, which shows in dotted lines the head and fingers advancedbeyond the position of the cross-bar. Movement is given to the gears L lto efl'e'et these 0 erations by means of a rack-slide L slidinorizontally in ways in the table A, (see fig. 3,) this reciprocatingmovement being given by the cam L through the lever L, pivoted to thecross-bar A at L and connected by an adjustable connecting-rod L withthe rackslide L The rocker-arm j is set on its rockshaft to begin themovement of the plate 5 before the plates K K begin to rise. The' platesK K are provided with hooks correlate J and for a" corres ending ur ose.is will be noted that during all t 's operation the blank is firmly heldin place by the pressure 7 ainst the former, the part of the blank w isto form the bottom of the box not being lifted thereby out of thecarrier.

After the box has been folded as above described it is necessary that itreceive pressure to insure the engagement of the surfaces during theirdrying. For pose I provide igllliinzireegl pressers M M, which reciprgzcats in slides 'forrhed*belh, the" table A by j etherend ofeachangle-arm is connected to an sdllustable link m, having a yoke m stradding a cam m, by mcans of which the necessary reciprocating movement isgiven to the link m to straighten out the toggle and break it Each (mm mis'mountorted in the frame A, and alsoi'n the" T es G for theplungerirame. Each stud m also carries a gear m whichis' in mesh with anintermediate gear are, which ets its movement from the gear as on the saft B. i

In order that while pressure is ap lied by pressers to the ends of thebox t e sides fer to provide ea cli pi'esse'i' 'Mwitha pair ofside-holders N. Each side-holder N consists of a wing vertically hin edat n in the face of thepresser M and heldiy means of a spring 11/ in aspreading position with relation to the other holder of its pair, aswill be understood from Fig. 13. Cam-surfaces are provided, as at n,upon suitable projections from the oke A by means of which the holdersare rought into position at right angles to the pressers M when theressers reciprocate toward each other, as is indicated in dotted linesin Fig. 13. Thus the nearer the press- A ers come together incompressing the ends of the blank about the former the closer are theseholders pressed against the sides of the blank, so that the box willmaintain its rectangular'form in cross-section during this pressing oeration.

After t e folding o eration has taken place as above described theformer and folower are started on their downward movement and brin thebox between the pressers, after whicl the pressers come to ether asabove described, and compress t e box about the former. The nextoperation is thestripping of the box from the former,a d

e this is accomplished by means of ooks Iv in it's forward each locatedon top of its presser and held in position thereon by means of a s rinM, at? tached to the pro'ection A. i e these hooks or strip ers project,as they must, slightly over t e opposing faces of the pressers, they donot interfere with the downward movement of the former and its box, forthe reason that the pressers are at that moment in their rear orseparated position. When the former has reached the lower extremity ofits stroke and the ressers are pressin against the box, these 0 earersor strippers slightly overlap the edges of the box, and in order toinsure their engagement therewith the former is preferably grooved, asshown at g. Just before the former begins to rise the pressers arewithdrawn sufiiciently to'release the pressure upon the box ends, andyet not sufficiently to withdraw the strippers M from over the edge ofthe box,- and' dwell momentaril in that position while the former rises,and pers is pulled off from the former, t e follower 1n the meantimedescending sufficiently far out of the way to allow the stripped box tofall into a receptacle below the machine. The ressers separatestill-farther when the box as been stripped to allow the follower torise and a fres folded blank to be brought between them.

The complete sequence of operations is as follows: The former being inits lowest pos'ition below the table A, the pressers being in theirpressing position, and the carrier being position it starts back to geteing enabled to do so while another blank,

The pressers then complete their rearwand movement.

It is evident that other means may be provided for accomplishing; thesame objects which I have accomplis b d in my machine above described.Themain object for which 1 am contending is the absolute registration ofthe blank with. the former and ioldin mechanism, so that a more eriectbox shall be constructed than, as I be love, has heretofore beenpossible. My main novel features, as I believe, consist in mechanismwhich shall com rise a recessed carrier to receive and hold t he blankby grippers or other suitable means, which carrier shall have absoluteand positive registration with the former, and the clamping of the blankagainst the former while the blank is still gripped the carrier, thecarrier thus serving not onlv as a carrier, but as a support for theblan during the folding operation. Another feature of novelty consistsin mounting the folding mechanism directly in the carrier, so that itnot only forms, in ell'ect, a part of the carrier for the purpose ofconveying the blank from the hopper to its folding position, but also,by reason of the fact that the blank is clamped without removal from thecarrier, folds the blank with great accuracy. about the former. Inthisconnection the neces sity for accurate folding at the base of thebox must be remembered, for an error at the base is magnified accordingto the length of the box, so that aminute error scarce distinguishableat the base may render thebox unmarketable because of its dimension atthe a open end of the box. There are also other peculiarities ofconstruction and movement of mymachine which I believe to be of valueand Importance in principle, the details ofwhieh, owever, may bematerially altered without do arting fromthe substance thereof.

Wind e1 have referred to the surface of the former o posite thatconnected to the stem as the ottom, I do not mean to imply that theconstruction of my 'machine may not be altered so that the clamp shallhave a downward -moveme nt to clamp the blank and the former andclampran upward movement tocarry the folded blank to the pressers.Moreover, this mechanism may operate laterally instead of vertically,the rest of the mechanism being designed accordinglz. It is alsoapparent that certain of the mec anism above described magabe usediniboxmachinesofother kinds. or example,.the recessed carrier may beused with other folding mechanism, and the folding mechanism may be usedwith adifierent type of carrier.

v A mechanism mounted on the pressers for preventin bulging during thefolding operation I believe to be new with me, and it is evident that itmay be operated by other means than those shown so long as it allows thebox to be placed freelybetween the pressers and then coasts with the boxduring the pressing operation and s thereafter moved to allow the box tobe Withdrawn.
